The Electromagnetic System of Units (EMU)
Description
The electromagnetic system of units (EMU) has the centimeter, gram, second, and biot as its base units, where the biot is energy-equivalent to the unit square root dyne (). For naming consistency, the biot is called the abampere.
When used in conjunction with the UseSystem command, the electromagnetic system sets the following units for the given dimensions.

Examples
Electromagnetic units can be converted to their energy equivalents.
If infolevel is set to a greater integer (possible settings are 1 through 5), more detailed information about the computation method is displayed.
convert/system: "converting to the units erg/s"
